They stay at 700 rpm until i apply gas to move off.
Now prior to service i'm sure they never dropped below 750/800 rpm.
My handbook does not give data for rpm so my question is:
Does anyone know what the tick over should be for the gd model, 1.4 l petrol engine?

Off-Topic:Can't help with the 1.4 petrol, but Vayda ticks over at a neat 752rpm.

Can't find the idle speed, but did find this.
1.4 Idle Speed Control.pdf - Google Drive (https://drive.google.com/file/d/0B8ANHWfNw-qjU1NMbnFDOUZ2WTA/edit?usp=sharing)
It would appear that the idle speed is not a fixed or tunable value.
An analogue tacho is not all that accurate, but better than nothing. I suspect, Shambles has a digital readout at his disposal. :D

:eek: "tick over", "gas", what language do you use over there. :razz:
We use the term 'tick-over' quite often, and I have sometimes used the 'gas' thing myself when meaning depressing the accelerator. Though gas seems odd now I think of it - as it is really an Americanism.
I don't remember what my 1.4 petrol ticks over at, though it is an FD so differently tuned.

What terms do you use?
I used gas as it is a universal word which is used rather than location specific word - juice - which i would have used.

= "accelerate"
Splitting hairs I know, but if you apply gas, all you are doing is raising the engine revs.
However, if you're in gear, then you apply power to the drive train and you'll move off.
:mrgreen: :wink:
Ah!
The joys of the English language. :winker:

Gas would be, power.
We do commonly have petrol engine vehicles using LPG, from Oz vast resources. No Dave's either way, really. :D

Anyway whatever the word(s) used in your neck of the woods does anyone have this data?

You can generally guage how much "real" info is to be had by how quickly a post goes off-topic. :winker:

It appears that the idle RPM is not a fixed number, so can't be provided. RPM is determined by the ISC as shown in my reply 3. The device resistance is measured and if in spec, then the engine is effectively at idle. The only way would be to accurately scangauge the motor.
Is there a member with a 1.4 & scangauge who can provide the numbers and help poor Saracen.

Back at dealers in 2 weeks for my new fob so i'll ask them for details.
It runs so so smooth at at this rpm but as it is summer here just concerned come the cold weather it may be running too low and cause the car to stall.
But then i'd expect the ecu to minitor outside temp and alter accordingly.
